Electronic traffic signs will be set up on expressways connecting Shanghai to Jiangsu and Zhejiang provinces by 2010, city officials said.
They also said a self-service toll system will likely be set up by that time to reduce waiting periods at expressway entrances.
"The signs will greatly improve traffic flow in the Yangtze River Delta region," said Zhang Yunjie, deputy director of the Shanghai Engineering Administrative Bureau.
Bureau officials said the signs will provide traffic and weather information on different expressways linking Shanghai with Zhejiang and Jiangsu.
The information will allow drivers to select an appropriate route.
They also said the city will have six expressways to Jiangsu Province and four to Zhejiang Province by 2010. Currently, there are three to Jiangsu and one to Zhejiang.
The number of private autos in Shanghai has increased nearly 40 times in the last six years and more people are driving to neighboring provinces.
Chen Youhua, a senior engineer of Shanghai Urban Planning Administrative Bureau, said: "The problem is some expressways are overloaded while others are not fully used, causing a waste of public facilities."
So far, the signs have been endorsed by governments in Shanghai, Jiangsu and Zhejiang.
Meanwhile, once the toll system is set up, drivers will use a smart card instead of cash, which should also speed up traffic flows.
On some highways a stop-free toll collection system based on wireless signals will be used.
Huang Guofu, a cab driver at Qiangsheng Taxi Company, said: "Hopefully, more electronic traffic signs will be set up downtown so that we can select routes early."
